Man found dead along Interstate 10 identified

Authorities have identified a man killed earlier this week while walking on Interstate 10 in Kenner as Reyes Joel Gomez Castro.

Gomez, 32, was hit about 8:20 p.m. Monday while walking beside the eastbound lanes of the road, said Lt. Brian McGregor, a Kenner Police Department spokesman.

A family member told police that Gomez was last seen leaving his apartment in the 2900 block of Kansas Avenue about an hour before the accident, on the way to a store. The relatives said they did not know why he would be near the interstate.

Gomez was from Guatemala and living with his brother in Kenner, McGregor said.

Investigators continue to try to find a white tractor-trailer that was headed east on I-10 without its trailer at the time of the hit-and-run.

Anyone who witnessed the accident or who has information about Gomez and his whereabouts before the hit-and-run is asked to call Kenner police traffic investigators Sgt. Jon Cryer or Officer John Terranova at (504) 712-2236.

Crimestoppers tip leads to robbery arrest

A Crimestoppers tip led police to arrest a 15-year-old youth in connection with a series of recent armed robberies in and near the French Quarter, New Orleans police said.

The suspect was not identified because of his age.

He was arrested Thursday at his home and booked on two counts of armed robbery and one count of attempted armed robbery for an incident that happened Dec. 7.

Police said they expect to book him in connection with other armed robberies thought to have been committed by the same three young men.

Detectives, meanwhile, have learned that another of the alleged robbers, whose identity remains unknown, goes by the nickname “Trill” and frequents the St. Roch neighborhood.

Anyone with information on the identity of “Trill” is asked to contact 8th District detectives at (504) 658-6080.
